Node not connecting to network

How to get started
1

Hi all,
I’m new here and am thankful for this forum and everything I have learnt this far.

Have set up a gateway RAK 7258 which the things stack community edition can see, and so I presume is working and I have set it up correctly.
Trying to set up end device RAK 7205. Keep getting “ERROR: RUI_AT_LORA_PARAMETER_INVALID 82”, which others have suggested means the dev key or app key aren’t set up, however the data suggests they are and the numbers match what is in TTN. I see “joined network:false” and cannot see the node through the web interface. I suspect a node set up problem, but I’m not sure what to try next as I’m very new to this. Below is the lora status if that’s helpful?!

Thank you for seeing if you can teach me some more problem solving skills!
Regards.

Try 0000000000000001

Whilst entirely technically correct that all zeros is preferred, it turns out there are many LoRaWAN stacks that just can’t cope with it as all Zeros.

ok thank you. WIll give a try and report back!

Unfortunately @descartes that didn’t seem to do the trick. Are there any other common mistakes/issues of which I should be aware do you think?

Changing the app_eui to a NON zero number worked for me. The hours that i wasted to find this out OMG.
